Design of motion-assisted training control system based on nonlinear mechanics

Abstract In order to improve the level of intelligent rehabilitation training equipment and assist patients effectively restore walking function, a motion-assisted control system based on nonlinear mechanics is proposed. According robot direction lower limb studied in this article, stable, safe, reliable mechanical structure designed optimize structure, anti-overturning stability static dynamic analyzed. Then, through human-computer interaction system, automatically realizes automatic forward backward, left right turn, anti-overspeed, anti-fall, other functions. A joint simulation platform speed was built using MATLAB ADAMS verify effectiveness algorithm. The results showed that users slowly increased their from 1 5, at approximately 0.3 m/s. user adapts during use process, training, improved slowly. Therefore, highly applicable, convenient for operation, with good performance, high stability, mobility ability.
